      This revision merges in many of the fixes for ANSI condition types · 42efe00d
      pw authored
      in various calls to ERROR. Those easily handled by using new condition
      types simple-file-error and simple-program-error are included.
      
      The only functional change here is that the function CHARACTER no longer
      accepts an integer argument so as to be ANSI compliant. This may
      break some code.

      Backout a previous hack of adding format-{control|arguments} protocol · 06be8c9a
      pw authored
      to serious-condition. Instead, have new internal condition types
      simple-package-error, simple-file-error and simple-program-error
      which inherit from simple-condition and respective error condition,
      thus picking up the format protocol from simple-condition.
      
      Noted a probable bug in that the CPL for conditions is not sorted
      which results in the found report method being dependent
      on the order of super-classes specified in the call to define-condition.

      Gray streams support: · 6c21ff8a
      dtc authored
      * Rename the 'stream structure class to sys:lisp-stream.
      * Add a new none hierarchical 'stream built-in class which inherits
        from: instance, t.
      * Hack in the new stream class as a mixin for the structure base
        lisp-stream class which now inherits from: stream, structure-object,
        instance, t.
      * Add a new 'fundamental-stream standard-class which includes 'stream
        as a mixin, and add PCL hacks to allow this to be redefined after PCL is
        loaded to be (defclass fundamental-stream (standard-object stream) ...).
      * Add appropriate support to the base stream functions to dispatch to
        the Gray stream functions for the handling of fundamental-streams.
        Some of the lisp-streams encapsulating CLOS streams still need
        a little work.

      This revision alters the condition type hierarchy to be in compliance · 4a42e17c
      pw authored
      with the ANSI spec. A default report method is attached to the
      serious-condition class and many of the uses of (error "string" arg..)
      in filesys.lisp and package.lisp were changed to use, for example,
      (error 'file-error :format-control "string" :format-arguments (list stuff))
      The end result is no obvious change to what the user sees, and enables
      one to establish a handler to catch the particular error type as
      mentioned in the "Exceptional Situations:" section of the CLHS
      write-ups. There probably are still some places where the error
      types need to be fixed.
      
      Also, a bug in with-package-iterator which caused failure with
      a null package-use-list was fixed, and some file functions (like
      truename and probe-file) now disallow a wild pathname.
